dc.description.abstract |
Lithium (Li) metal has been regarded as an ideal anode for energy storage system because it has high theoretical specific capacity (3860 mAh g-1) and the most negative electrochemical potential (-3.04 V versus standard hydrogen electrode) and it is the lightest metal (0.534 g cm-3). On basis of these outstanding features, the combination with Ni-based intercalation-type layered oxides that can deliver a reversible capacity of ~200 mAh g-1 will conduce to the realization of high-energy density batteries. However, dendritic Li growth and low Coulombic efficiency (CE) of Li plating and stripping reaction place a hurdle the practical uses of Li metal on batteries due to safety concerns and low lifespan of battery.4,5 To resolve these critical issues, a considerable exertion has been made to find desirable electrolyte systems including high salt concentration, sacrificial additives protecting reactive Li metal and less reactive solvents. The use of ether-based electrolytes to lithium batteries with 4V-class cathodes have been precluded, mainly due to their low upper voltage limits of lower than 4 V vs. Li/Li+ and high flammability causing the safety concerns of batteries. Here, we present tailored electrolyte systems that can provide a solution for long-lasting Li metal batteries without sacrificing energy density, by constructing a controlled and robust solid electrolyte interphase. The interfacial engineering of electrode materials by electrolyte additives offers great promise for high-energy-density batteries. |
